    How this cron expression parser works

    1. 01 Type or paste a standard 5-field cron string.
    2. 02 Optional examples fill common schedules (weekdays, monthly, etc.).
    3. 03 Fields are expanded (*, ranges, steps) into match sets.
    4. 04 The visualizer walks minute-by-minute to list the next matching runs.

    Frequently asked questions

    What cron format is supported? +

    Standard 5-field cron: minute hour day-of-month month day-of-week. Some 6-field strings are accepted by dropping a leading seconds field.

    Are next runs in UTC or local time? +

    Local browser timezone, formatted with your locale settings.

    Does day-of-month and day-of-week use OR logic? +

    Yes when both are restricted (neither is *), matching common cron semantics where either field can match.
